Long-Distance 1/N_c Corrections to Density-Density Operators in K --> pi pi Decays
Abstract
Description
In this talk we discuss the general method to calculate loop corrections to Delta S=1 density-density operators in the 1/N_c approach. As a result we present the long-distance evolution of the operators Q_6 and Q_8 to O(p^0/N_c) in the chiral and the 1/N_c expansions.
